A striking image of the Milky Way's magnetic field, based on data from the European Space Agency's Planck satellite, is circulating among space enthusiasts. The map shows polarised light from galactic dust tracing the galaxy's magnetic field lines, credited to ESA, Planck, CNRS, IAS and Paris-XI University. It is being shared as an example of the beauty and value of astrophotography and public space science data.
